Artificially hatching eggs

Recommended Posts

kthien

Hi all,

I managed to save a good amount of eggs (70-80) from a golden neocaridina and am attempting to hatch them in an egg tumbler. I noticed that they started to grow a white fuzzy-like growth around them, which may be attributed to the clear membrane that I was too lazy to remove or the notorious, deadly fungal growth. I'm more-so experienced in raising Corydoras than shrimps, and these would be removed from the tumbler to avoid fouling the rest. However, I spoke to an experienced breeder who stated that she had successfully hatched ones like these, and so I thought that there would be no harm in trying (in a separate tumbler).

I promptly removed the eggs and performed a dip in a diluted methylene blue bath. Will see how they go.

Good luck with this, there are a few on here that have succeeded doing this so it is worth trying!

Good luck! I'm doing the same thing right now with some tangerine tiger eggs dropped in a moult, I don't have a tumbler though so I'm using a net over an airstone.

Hey guys,

Guess today was the day. This was one of many. I was doing a dip every 2-3 days, for about 5 seconds, whether it helped or not, I'm not entirely sure!

FANTASTIC! You must be thrilled and all the effort was was clearly worth it. They will be very fragile so you aren't totally there yet as they could still perish but I have my fingers crossed and well done!

Thanks Simon! It was a nice surprise, especially with the ongoing issues with the tank. I might stop h2o2 treatment now with them being born and all.. What are your personal go to foods for keeping them alive? and feeding frequency?

Are they in the tank or separate? In an established tank they will probably just survive on biofilm, especially if there is a limit number of them. I use Bacter AE which encourages biofilm growth and I'm not sure whether the shrimp eat it as well as they sually make a beeline for it? I used to feed the shrimp a Chi Ebi baby shrimp food. Both bacter AE and thebaby shrimp food are powder and I dip about 5mm of a wooden stick (match etc) in the water, then into the product, knock off excess, and then swirl in the tank! I did this twice a week. I don't honestly know whether feeding the babies made any difference but the tank was very well stocked with shrimp by that stage, so it probably must have helped. There are a few baby shrimp foods, most makes do one and they will be powder.

If you move them from one tank to another you should drip acclimate them over a good few hours, even if the parameters are pretty similar, especially when they so small/young.

Baby shrimp tend not to move far from one spot to start with and hide often so you may not see much of them in a normal aquarium setting until they have settled in.

Congrats and well done on hatching your shrimp artificially.

      Good to see you back, I assume all is doing well! As you are transferring everything from one tank to another, and using a neutral substrate (gravel) you can probably do it in one go. If you are getting a new filter as it is a larger tank then I would float the sponge from the new filter in the 5L tank for a week or two to get some bacteria on to it, but it looks like you will be transferring your existing filter which can just be transferred as it is. If you are using some sort of active soil substrate you will need to run that in to avoid any ammonia spikes or other build up of nutrients etc before that is put into the new setup, but you say gravel so this is probably not relevant. I assume you will catch the shrimp and put them somewhere safe whilst you do all the tank work so I would drip acclimate them for a couple of hours to the new water to be safest, once you have completely set up and filled the new tank! If they are neocaridina shrimps you are transferring and the water parameters are very close you would probably be able to miss the drip acclimating, but I would play it safe and drip acclimate though! You will also need to ensure the water temperature is matched when you go to put the shrimp in the tank as the shrimp may have been in water that has cooled over the time they were put to one side. How are the tanks doing, and did the small micro crabs work out? Simon

      Hello everyone, lately I've been thinking of upgrading a tank of mine from a 5 gal into either a 10 or 15 one. So I plan to move all the stuff and shrimp from the 5 gal into the new one. I'll use the same gravel and the same water for the new tank and the filter and plants will come from the 5 gal. My question is, do I still need to cycle it separately with a new seeded filter or is the whole using a mature filter okay? Also is skipping drip acclimation when the water params are almost identical acceptable?

      Sorry to hear you have lost half the remaining shrimps. At least you have another taiwan bee tank which is doing fine. Be careful not to take anything (including shrimp) from the bad tank and put it in the good tank! It could be an infection as LukeBeveridge above, maybe some shrimp were sick when you got them. Time to start thinking/preparing to start that tank again! If you are using something different in the tank that you aren't using in any other tank then use what has worked well with the other tanks. At least there is no rush so you can do it at your leisure, and once it is up and running you should have shrimplets you can transfer from your other tank! There is a device out there to prevent heaters overheating by cutting the power to the heater when it gets too hot, it probably would be worth getting one of those, at least for the taiwan bee tank(s).  The parameters look fine. The nitrate figue may indicate the tank isn't cycled properly, but I have a tank that has nitrate 25 permanenetly for 5+ years with no problems. You could test the nitrates in the other taiwan bee tank and see what they are out of curiosity, but as I assume you will be re-setting up the bad tank it probably may be better to just get ready to do that. I feel your disappointment have a tank that is exactly the same and I have (temporarily) given up on that (as I don't know what the problem is) and just have fish in it for now, but I would have to start again if I want to start with taiwan bee shrimp again......

      That is a beautiful shrimp! Mixing different colours as you are will mean you will get offspring reverting to wild (brown or clear usually) quite quickly. Simon

      In that case, I would be inclined to think that this is an offspring of the Yellow/Green you have in the tank. Congrats. You have created a new colour morph.
